Ok, I have a 289 I'm building up and would like to put alot of parts that I have from a 5.0 liter on the front....mostly because I want to use the serpentine belt and underdrive pulleys.

I've heard that the water pump on a 289 and 5.0 spin the opposite direction. Is this true? If this is the case wouldn't it also spin the cam the opposite direction and not allow the engine to run (exhaust valve would open and close before intake valve)? Can the serpentine belt be routed a different way and a 289 water pump be used?

Questions....questions....questions.....

The routing of the serpentine belt is what changes the waterpump direction, not the cam or crank rotation. Just change the timing cover and waterpump to the 5.0 parts and you'll be fine with the 5.0's serpentine belt. Good luck,

MAN WHAT AN IDIOT!!!!!

You're right, timing chain drives the cam.... and the crank pulley drives the serpentine belt which drives the water pump. I was having a brain fart there.

So just route the belt the same as on a 5.0 and hook up the hoses to the radiator and go on down the road.

Is the lower hose on the radiator on the passenger or drivers side on a 68 Mustang.....will I need to change the original radiator to a Griffin or something else in order to have the top and bottom hose on the correct side? I think the top needs to be on the passenger side and bottom on the drivers side.

On a '68 the lower and upper hoses are on the passenger side. On the later models the lower was moved to the driver's side. I've had a radiator shop move the lower inlet of the radiator for about $30.00. Hope this helps!

One other thing, If you use the front cover from the 5.0, you will have to drill a hole for the oil dipstick tube.

I'm using the timing chain cover from the 289 and everything seems to fit correctly.

The timing chain cover from the 289 won't work with the 5.0 water pump. Check it again, you need the 5.0 cover too.

Also, doesn't the 5.0 cover not have the manual fuel pump hookup? If so, you might need to get an electric fuel pump too.

Another thing, though I can't say for sure, but I think the 5.0 accessories bolted up to a hole in the driver side head, which I do not think exists on early 289 heads. Might be worth looking into if you are installing both the PS pump and the AC pump. Since your using the 5.0 timing chain cover I don't think there will be any issues with the serpentine belt tensioner..

If you have any friends with a 5.0 installed I would do a long hard look at everything that is hooked up just to make sure your not missing anything.

Check this out the a conversion kit!

http://shop.store.yahoo.com/mustangweekly/mf-8501-a50.html

or another option is

I am searching for something otherthan the March serpentine belt conversion because it costs about $600 plus. Not willing to pay that much without finding other options.

Perfect place to ask a question. What IS the ADVANTAGE of serpentine over v-belts?

Mellow,

Serpentine belts are self adjusting and you only need one belt. Plus they last a long time. But other than that, I like v-belts better.

Anybody know what the stock 289's rear-end of a '68 Coupe was? 8 inch? 9 inch?

8", unless it was a hi-performance car.
